IMPROVEMENT IN WAGON-BRAKES.

Specificationforming part of Letters Patent No. 201,423, dated March 19,1878; application filed February 20, 1878.

To all 'whom it may concern:

Be it known that we, FRED. A. KEENE and GYPRIAN VAN ORDER, of Marengo,Iowa county, and State of Iowa, have invented a new and ImprovedWagon-Brake; and we hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making part of this specication, in which- Figure 1 is a planview of our brake as applied to the bottom of the wagon-body, and Fig. 2a side view.

The object of our invention is to provide a safe, sure, and economicalwagon-brake and it consists of two semicircular brake-bars having` thebrake sh'oes attached directly thereto, in combination with certainoperating devices, as hereinafter more fully described and claimed.

In order that those skilled in the art may make and use our invention,we will proceed to describe the manner in which we have carried it out.

In the'said drawings, A B C are three guiding-loops bolted to the bottomof the wagon-bed-A and B longitudinally, and C transversely, as shown.

Two semicircular brake -bars, D E, lie in these loops, their peripheriesapproaching each other closely in loop C, and on their outer ends theyhave clamped brake-shoes F G. To the opposite end of the brake-bars arepivoted two rods, H I, which are also pivoted to across-head, J, whichis centrally pivoted on a rod,K, connected with alever, L.

The lever L is pivoted at t near the edge of the wagon-body, and itsopposite end is linked to a sliding treadle, M, or foot-piece,conveniently located to be operated by the driver. When the foot-piece Mis pushed forward the inner ends of the brake-bars are forced forwardand the brake-shoes forced outward, as shown in dotted lines. p

On pivots in loops A B are friction-rollers e e', against which the rimsof the brake-bars bear to facilitate their movement.

As a modication of our device, we propose to place cog-teeth on asegment of each brake-bar, and between them place a toothed bar, P,having corresponding teeth, all interlocking and held within the loop C,and the bar P being guided by the small loop a, and provided with meansfor direct attachment to lever L. Y

It is evident that the movement back and forth of the toothed bar will,by means of the toothed segments, throw the brake-bars in and out.

Having thusdescribed our invention, we claim as new and desire to secureby Letters Patentc 1. The semicircnlar brake-bars D E, in combinationwith the shoes F G, substantially as and for the purpose described.

2. The semicircular brake-bars, in combination with rods H I, cross-headJ, rod K, lever L, foot-piece M, and loops A B C, provided withfriction-rollers e e', as set forth.
